FCF = furocoumarin free. Naturally, bergamot is highly phototoxic and it
can cause your skin to react badly to ultra-violet light rays, such as
those from the sun and tanning beds. Adverse reactions include
blistering, loss of pigmentation and rashes. Coumarins are the
phytochemicals that gives it its photo-toxicity. Our bergamot oil has
been treated to remove the coumarins. While we generally as a rule
recommend that only natural non-rectified oils are used, due to
bergamot's potentially adverse effects here we make a well-researched
exception, as many other aromatherapists do.
